Or some random pony shows up, wishes it dead, and everything returns back to normal. Starlight can join his filly and wife, Twilight returns to her friends in ponyville, and Celestia returns to Canterlot.

Yes, but that was the pun. The plot-line was using misunderstanding a prophecy for the characters involved to get all worked up, and then relief over the misunderstanding being cleared up for the viewer.

Great so Starflare was right he will never see his daughter again, he already deduced that to destroy the crown would cause his death.........I love this character and feel saddened he will die, though I hope harvest dies with him. Though a genius would figure out how to get harvest to want to destroy the crown and destroy it.
